Detailed description of the invention
Further describe the present invention below in conjunction with drawings and Examples, but protection scope of the present invention is not limited to this.
Referring to Fig. 1, ultrasonic tool head of the present invention is torus shape or similar torus shape, the solid core ultrasonic wave radiation head of similar torus shape that ultrasonic tool head comprises annulus end face 1, lower annulus end face 2, inner curve 4, outside curve 3 and surrounded by above-mentioned face simultaneously.The material of ultrasonic tool head is common conventional metal material, can be the one in titanium alloy, steel alloy, stainless steel, aluminium alloy and copper.Ultrasonic tool head is provided with the installing hole 5 for connecting ultrasonic transducer or ultrasonic transformer, and installing hole 5 is provided with internal thread, for being threaded with conventional ultrasonic transducer or ultrasonic transformer by bolt.Ultrasonic tool head of the present invention is connected with ultrasonic transformer, ultrasonic transducer and ultrasonic wave driving power successively and namely forms a complete ultrasonic wave emission system, wherein, the point of excitation of ultrasonic tool head is arranged in outside curve 3 or inner curve 4, according to the difference in the inside and outside footpath of ultrasonic tool, the conventional Ultrasound wave transducer of different size or ultrasonic transformer can be selected to be attached thereto.
Referring to Fig. 2-4, the shape of ultrasonic tool head cross section is the one in annular, oval annular and fan annular.Referring to Fig. 1, cross section is the ultrasonic tool head of annular, referring to Fig. 2, cross section is the ultrasonic tool head of oval annular, and referring to Fig. 3, cross section is the ultrasonic tool head of fan annular, the arc of its middle fan annular can be major arc or minor arc, can determine according to practical application.According to different application requirements, ultrasonic tool head can be arranged to torus shape, oval torus shape or fan ring body shape, all can reach technique effect of the present invention.

Ultrasonic tool head at least has the first circle ring surface of an employing flextensional mode radiate supersonic wave, and the first circle ring surface can be inner curve 4 or the outside curve 3 of ultrasonic tool head.Can set up the second circle ring surface for radiate supersonic wave, now, the first circle ring surface and the second circle ring surface are respectively inner curve 4 and the outside curve 3 of ultrasonic tool head simultaneously.First circle ring surface and the second circle ring surface are the Ultrasonic Radiation face adopting flextensional mode radiate supersonic wave, and the ultrasonic wave tranmitting frequency arranging the first circle ring surface is identical with the Ultrasonic Radiation frequency of the second circle ring surface.As required, ultrasonic tool head also has the 3rd anchor ring for radiate supersonic wave and the 4th anchor ring, and the 3rd anchor ring and the 4th anchor ring are respectively the upper annulus end face 1 of ultrasonic tool head and lower annulus end face 2.
Common ultrasonic transducer or ultrasonic transformer mainly do extensional vibration, but theoretical according to ultrasonic wave, extensional vibration can inspire the vibration frequency of other pattern, for example, oscillation crosswise, tangential vibrations, twisting vibration and flexural vibrations etc.Generally, the amplitude of these vibration modes is very weak, very little on usually required extensional vibration impact, but by the material of tool heads, size and in conjunction with structural design of the present invention, other vibration modes are inspired by the extensional vibration of ultrasonic transducer or ultrasonic transformer, and make the vibration frequency of required vibration mode consistent with the driving frequency of extensional vibration, just can excite and strengthen required mode of vibration.The present invention uses ultrasonic compressional to go out the flexural vibrations of tool heads radial direction to vibrational excitation, makes inner curve 4 and outside curve 3 become radiating surface.Simultaneously, make the frequency of tool heads flexural vibrations consistent with the stimulating frequency of ultrasonic wave extensional vibration, and this flexural vibrations of conscious reinforcement, to reach the effect of a resonance, thus make the inner curve 4 of tool heads and outside curve 3 all produce strong ultrasonic wave vibration.When vibrating, the internally radiation of the first circle ring surface, the second circle ring surface, to periphery radiation, considerably increases the swept area of tool heads.The use of flextensional mode, changes the direction of transfer of vibration, improves the flexibility that tool heads uses, makes the vibration of the first circle ring surface and the second circle ring surface reach resonance simultaneously, add the oscillation intensity of the first circle ring surface and the second circle ring surface.
